What type of signage should be displayed to prevent alcohol service to minors?

Displaying legal drinking age signage is vital in preventing alcohol service to minors because these signs clearly communicate the minimum age requirement for purchasing and consuming alcohol. By informing both staff and patrons of the legal restrictions, such signage helps create a responsible drinking environment. It serves as a constant reminder for employees to check identification and enforce age restrictions rigorously, thereby reducing the risk of underage drinking.

In contrast, general advertising signs, promotional discount signs, and happy hour signs do not focus on the legalities surrounding age restrictions and may not effectively convey the seriousness of avoiding alcohol service to minors. These types of signage primarily aim to promote sales or special offers, which could divert attention from the responsible service of alcohol.
